I live in a Garden flat in Riebeeckstad, I pay R4.42 per unit, where the rate is supposed to be R1.80 per unit. I phoned the meter compony Citi'q and asked them a few questions. They told me this rate is too much and the owner should phone them so it can be lowered. Someone told me there is a law that the landlord can't ask more than 10% of the rate ( 1.80 ). what can I do ?
